VLSI layout of an inverter circuit using Magic software. Magic is an electronic design automation (EDA) layout tool for very-large-scale integration (VLSI) integrated circuit (IC) originally written by John Ousterhout and his graduate students at UC Berkeley. Work began on the project in February 1983.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Initially PCB was not intended to be a professional layout system but as a tool for individuals to do small-scale development of hardware. [ 1 ] [ 3 ] The second release 1.2 introduced user menus. This made PCB easier to use and increased its popularity. [ 1 ]
EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features. EAGLE stands for Easily Applicable Graphical Layout Editor (German: Einfach Anzuwendender Grafischer Layout-Editor) and is developed by CadSoft Computer GmbH.

An integrated circuit layout editor or IC layout editor is an electronic design automation software tool that allows a user to digitize the shapes and patterns that form an integrated circuit. Typically the view will include the components (usually as pcells), metal routing tracks, vias and electrical pins.
[3] [4] [5] Electric is used to construct logic wire schematics and to perform analysis of integrated circuit layout. It can also handle hardware description languages such as VHDL and Verilog. The system has many analysis and synthesis tools, including design rule checking, simulation, routing, Layout vs. Schematic, logical effort, and more.
At this point it is said to be "LVS clean." (Mathematically, the layout and schematic netlists are compared by performing a Graph isomorphism check to see if they are equivalent.) In most cases the layout will not pass LVS the first time requiring the layout engineer to examine the LVS software's reports and make changes to the layout.
